The sequence in which 14 laboratory rhesus macaques left their home enclosure during a routine catching procedure was recorded on 30 occasions during 6 weeks. The animals were trained to voluntarily exit one by one...
Training technique is described. Thirty-seven [group-housed] captive chimpanzees were trained using operant conditioning to enter a transfer box. [Age and sex of subjects is not provided.]
This study demonstrates that only a minimal time investment was needed to train a large troop of laboratory non-human primates to co-operate in the catching procedure. A group of 45 rhesus macaques (Macaca mulatta) was...
Open-field behaviour of individually gentled and nonhandled adult male Wistar rats was studied in a mildly novel test situation. The gentled rats were more active and showed fewer signs of fear on the first trial...
Caretakers should seek knowledge of the natural lifestyles of the primates in their charge, and attempt to reproduce in the captive environment the salient aspects of the natural habitats that are biologically relevant to the...
A survey of 75 biomedical articles dealing with stress-dependent blood parameters in caged primates revealed that the conditions under which blood collection occurred were in most cases [72%] described either not at all or so...
The prevailing housing and handling conditions of monkeys in research institutions is described. The present situation in primate research laboratories strongly suggests that professional judgment is no guarantee that the inhumane housing and handling conditions...
Neonatal (early) handling (EH) and environmental enrichment (EE) of laboratory rodents have been the two most commonly used methods of providing supplementary environmental stimulation in order to study behavioral and neurobiological plasticity. A large body...
Captive rhesus macaques are not intrinsically aggressive, but poor husbandry and handling practices can trigger their aggression towards conspecifics and towards the human handler. The statement 'rhesus macaques are so aggressive animals' is probably based...
Using positive reinforcement, J. McKinley trained 12 common marmosets (Callithrix jacchus) to provide urine samples on request. The study then exposed the marmosets to mildly stressful, routine husbandry procedures (i.e., capture and weighing). The nonhuman...
